+"""Agent Workflow - Content Review with Quality Routing.
+
+This sample demonstrates:
+- Using agents directly as executors
+- Conditional routing based on structured outputs
+- Quality-based workflow paths with convergence
+
+Use case: Content creation with automated review.
+Writer creates content, Reviewer evaluates quality:
+  - High quality (score >= 80): → Publisher → Summarizer
+  - Low quality (score < 80): → Editor → Publisher → Summarizer
+Both paths converge at Summarizer for final report.
